Be it known that I, KARL Wnasina, a sub- 5 jcct of the Emperor of (llerinan and a rcsii dent of Ililssen-ltuttenscheid, Germany, have 1 invented certain new and useful improvements in TlIIlG-FUSOS, of which the following is a specification.

The present invention relates to those mechanical time-fuses which are timed through the medium of a readily-rotatable cup covering the fuse mechanism, and has for i ts object to construct the cap in such a manner that it autrnnatically becomes fixed on iliring. i in the accompanying drawing, which is i axial SQ .tion of the forward part oi a tell having the fuse applied, the invention is shown, by Way of examole, as embodied in the fuse forming the subject-matter of ed States Patent No. 728,151. to Carl ihe construction and mode of operation of the fuse mechanism. is old, as also is the througl'i which adjustment of the nition results iron: turning the cap therefore unnecessary to "further hese features. The timing-cap A v rotatable on the cylindrical trun seat 6'' of the iuse-body,B that-it can d by hand Without the use of al like. Pins (2, which screwed e A, engage in an annular groove union Z2 and prevent axial discement oi the cap. in the partof the cat it surrounds that portion of the. trunnion 5" located in advance of the groove 1) is provided an annular groove o so that the Wall of the cap at this point is considerably v6 nod. At the moment of bring a projectile proried with this im )roved fuse the portion of j be cap weakened by the groove it yields to l e force of inertia of the part of the cap that j Specification of Letters Patent.

I laviw thus described in invention. What a .l

I claim, and desire to secure by Letters Patent, is-

I. A time-fuse having a circuinferentiallvadjustable setting means adapted to yield under the force of its inertia to be retarded relatively Lethe forward movement of a projectile, at the time of firing, and constructed to interlock by such yielding, against n1ove-- went in the direction of its adjustment.

2. A time-fuse, having a rotatably-adjustable cap constructed to yield under its own inertia and bind against a relatively fixed part, at time of firing.

3. A time-fuse comprising afuse-body, and

a cap rotatably adjustable on the use-body and having its well weakened to permit the cap to yield at the weakened place at time of firing,under the inertia of a. part of the cap, and cause the cap to bind against the fusebody.

4. A time-fuse, provided with and a cop, bet-ween \vhicn there is rotary adjustment in timing the fuse; said ca having a circumferential groove in. its walsurrounding said seat, to permit the portion of the cap thus weakened, to yield, on. firing, under the inertia of the part or the cap in advance of the groove, and to perinenently bind against said seat.

The foregoing specification signed at Dusseldorf this lhth'rlay of January, 1906.
